Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542476, here are decompositions:

19 + 31542457 = 31542476
37 + 31542439 = 31542476
79 + 31542397 = 31542476
103 + 31542373 = 31542476
313 + 31542163 = 31542476
373 + 31542103 = 31542476
409 + 31542067 = 31542476
439 + 31542037 = 31542476

Showing the first eight; more decompositions exist.
